South Korean Ban Ki-Moon is the current Secretary-General of the United Nations and has held the position since 2007.

Ban Ki-Moon is the first South Korean to ever hold the important post and has been at the forefront of several important reforms at the U.N. - from peacekeeping to employment practices.

The 66-year-old has also been outspoken on several issues including global warming and the situation in the Darfur.

However, Mr Ban has also been criticized in the past for not speaking out on controversial issues.

And while he's been compared to his predecessor Kofi Annan - known for his charismatic and media-savvy style - Mr Ban says his approach is "quiet diplomacy" and achieves much more behind the scenes and in one-on-one meetings with world leaders.

Ban Ki-Moon is currently at the World Economic Forum in Davos to work with other world leaders on issues like nuclear and food safety.

Here's your unique opportunity to have your questions answered by the Secretary-General of the United Nations.

In search of something different, author Connor Grennan undertook the adventure of a lifetime by taking a trip around the globe for one year.

Connor Grennan is your Connector of the Day.

Before taking in the majestic and beautiful sights of far-flung regions, Grennan started things off by volunteering at the Little Princes children's home in Nepal for three months.

However, while he was there, he soon found out that the place wasn't your typical 'orphanage'.

The home was actually a place where children were abandoned after being taken from their parents. Child traffickers were promising families in small villages to protect their kids from civil war - for a huge fee - by taking them to safety.

Instead, they would be left to fend for themselves in the chaos of Nepal's capital, Kathmandu.

Grennan undertook the task of trying to reunite the children with their parents and dedicated much of his time to that goal.

Here's your chance to quiz Connor Grennan on this difficult task.
